9 Claims.

The present invention relates to separable fasteners employing closure links coupled by means -of a movable slider, and has particular reference to a novel one-piece construction for `a. multiple fastener.

It is the principal provide a multiple fastener which utilizes two special type tapes, each tape being one piece construction, and carrying Another object of the invention is to provide a. multiple fastener which is not appreciably thicker than a single fastener.

Still another object of the invention is to provide a multiple fastener which is hermetically sealed against fluid leakage by means of interlocking sealing edges.

A further object is to provide an improved slider which automatically interlocks the sealing edges and prevents distortion and jamming of the fastener parts. J

With the above and other objects and advantageous features in view, the invention consists of a novel arrangementV of parts more fully disclosed in the detailed description following, in

conjunction with and more specically dened pended thereto.

two sets of closure links..

It has been found desirable to provide a separable fastener, which has two tape sections, each woven to carry several sets of closure links, and a single slider which simultaneously couples or 5 uncouples the cooperating closure link sets of the object of the invention toI I position the edge the form of an integrally two tape sections. Further, it is preferred to provide the two tape sections with interlocking or overlapping edge portions, to thus obtain a -iiuid seal when the sets of closure links are in coupled relation, the slider being constructed to portions in the desired interlocking or overlapping relation when coupling the sets of closure links.

Referringto Figs. l to 10, which illustrate one embodiment of my invention, the separable fastener assembly includes two tape sections I0 and II and aslider I2. The tape section I0, see Fig. 3, is initially woven to provide a garment attaching portion I3, a closure linkA carrier I4 which is preferably in the form of an integrally woven warp thread of large diameter, a body section I5, which is shaped by the slider, a second closure link carrier I6 which is also preferably in woven warp thread of large diameter, and a sealing portion I1, also with an end enlargement I8 in the form of an integrally woven large diameter warp thread or cord. Two sets of closure links I9, 20 are respectively secured to the carriers I4 and I6. The tape element II, see Fig. 4, is made complementary to the tape element I0, and is provided with similar and corresponding partys, designated |30. to 20a., respectively.

When the parts are in coupled relation, as shown in Fig. 5, the closure link set i9 is coupled with the closure link set 20a, with the sealing portion I'Ia underlying these coupled link sets, and the closure link set 20 is coupled with the closure link set I 9a, with the sealing portion Il overlying. these coupled link sets, whereby a double sealed' coupling results, this double sealed coupling having substantially the same thickness as a single coupling, as the double sets are adjacent instead of overlying. Moreover, only two specially woven tapes are used, thus simplifying the manufacture and assembly of the parts.

The slider I2 has a base 2| to which the usual manual pull tab 22 is swivelled, and includes two' l 2,325,382 '7. A slider element for a separable fastener` also secured to said connector element in adja-l lcent relation to said rst coupler element, the

operative parts of one coupler element being reversely disposed with respect to the operative parts of the other coupler element.

9. A slider element for a separable fastener comprising a connector element having guide means including arcuate guide recesses adapted to receive tape sealing portions provided with Vedge cords, a coupler element secured to said connector element, and a second coupler element also secured to said connector element in adjacent relation to said first coupler elementfthe operative parts of one coupler element being reversely disposed with respect to the operative parts ofthe other coupler element.
